Book excerpt: The complexity of decision making in thoracic surgery is growing exponentially. As new technology is introduced, physicians from nonsurgical specialties offer alternative and competing therapies for what was once the exclusive province of the thoracic surgeon. In addition, there is increasing knowledge regarding the efficacy of traditional thoracic surgical therapies. How to select among these varied and complex approaches is becoming increasingly difficult. The first two editions of this book have found wide acceptance among practicing surgeons, trainees, and educators. Chapters from them are regularly cited by the Thoracic Surgery Directors Association as valuable resources for their weekly curriculum exercises. As in the first two editions, chapters adhere to a specific format (updated for the third edition). This approach provides uniformity to the presentations, making it possible to identify useful material at a glance.
